The present invention relates to a keyer capture system for an electronic keyboard musical instrument, such as an electronic organ. The system is particularly adapted for the situation wherein a relatively low number of notes are required to be captured at one time, such as in the case of the pedals. The system is responsive to serial data for the pedals and the two keyers are captured on a priority basis with the master keyer given preference. If the note is already captured by the other keyer, then that note will not be captured by the keyer which is receiving the keydown pulse for that note, and a recirculating shift register for each keyer keeps track of which note that keyer has captured. The system is capable of being easily integrated into an electronic organ wherein the pedal data is in serial time division multiplexed format, and can be implemented as an accessory wherein it is desired to generate the pedal data from the lowest actuated key on one of the manuals.
